Five more professional baseball players have connections to a South Florida clinic at the heart of a widening doping scandal, according to documents obtained by “Outside the Lines.”

The new players listed in documents from the Biogenesis of America clinic run by Anthony Bosch: San Diego Padres shortstop Everth Cabrera, 26, the reigning National League stolen-base champion; Jordan Norberto, 26, a lefty reliever with the Oakland A’s; Fernando Martinez, 24, a Houston Astros outfielder; Fautino De Los Santos, 27, a reliever claimed off waivers by the Padres; and Cesar Puello, 21, a top Mets outfield prospect.

Sources said the players, like those who have been named in previous Biogenesis documents, were on a list as having received performance-enhancing drugs, although the documents are not proof that the players either received or used PEDs.

According to two sources familiar with Bosch’s operation, however, the Washington Nationals’ Gio Gonzalez, previously identified as being named in Biogenesis documents, did not receive banned substances from Bosch or the clinic.

Both sources, speaking independently, identified Gonzalez as the only Bosch client named thus far who did not receive performance-enhancing drugs. A document obtained by “Outside the Lines” bolsters their case: On a computer printout of clients, Gonzalez, identified by the code name “Gladiator,” is said to have received $1,000 worth of substances, but under “notes” are several substances not banned by Major League Baseball: “gluthetyn” (which a source said was a misspelling of glutathione), “IM [intramuscular] shots” and amino acids.

Glutathione is an anti-oxidant, and one source said the “IM shots” Gonzalez received were “MICs,” a medically dubious but legal combination of methionine, inositol and choline, often used for weight loss.

At least 25 players, either by name or nickname, are identified in the Biogenesis documents. Sources have indicated the number of MLB players who dealt with Bosch over the years could be significantly higher.
